Typically solid when used for gardening? I don't understand the argument here. Sprinkler valves are rated for water pressure. A plastic sprinkler valve would likely fail in the exact same way a PVC storage tank would. Use a valve rated for air pressure if you are even remotely concerned with safety. Water is incompressible and behaves completely different than air when pressurized. Please refer to the countless other threads here where this has been discussed before. Bottom-line; please don't cut corners when people’s safety is at risk.
